[Amps] Fwd: Pi-L In-circuit Adjustment Question

[TexasRF@aol.com]

Hi David, it will absolutely be helpful. Heck, the grid dipper test is  
helpful. We have been arguing over er, discussing, such a small difference in  
frequency that it is basically a trivial difference.
 
The only gottcha is that the tube and other nuisance reactance (strays)  will 
be added to your plate tuning C value. The net effect is when everything is  
finally connected, the plate tune C will end up at a lower setting. No matter  
though, this why there is a knob on it; we just can't always predict the 
exact  total of the extra C contributors. As the frequency is lowered, this 
naturally  becomes less of an issue and when raised, more of an issue.
